3M(TM) Structural Adhesive
3M™ Structural Adhesive SA5027 is a two-part epoxy, formulated for hem flange bonding applications on aluminium, steel or SMC. It features broad off-ratio and over-bake tolerance, and structural bond strength on untreated surfaces with high-draw lubricant.
  • Tolerates very high-draw lubricant coating weights
  • Robust, structural bonding performance even on untreated substrates
  • Can be dispensed with commercially available dispensing systems; broad off-ratio tolerance
  • Room temperature strength build; permits spot induction cure with cohesive failure mode
  • Controlled reactivity; balance of longer open time before induction with fast lock-up after induction
  • Extended open time allows for greater processing latitude
  • Broad curing windows; faster cycle times and low induction temperatures minimize risk of panel distortion
